摘　　要：介绍了动态冰蓄冷系统的制冷机组优先、融冰优先、定比例控制和优化控制几种控制策略,通过对各个时段冷负荷融冰需求进行优先度排序,提出动态冰蓄冷系统的经济最优控制策略并实现了计算机自动分析,最后以某建筑为例对比不同控制策略下运行费用。经济最优控制策略可以确保空调系统满足冷负荷需求,并有效降低其运行费用。Several control strategies of ice storage system are introduced, including chiller-priority control, storage-priority control, rate control and optimal control. According to the priorities of ice storage use of 24-hour periods, an optimal control strategy is proposed to make the dynamic ice storage achieve economical operation, and software is designed for computer-aided analysis. Finally, by an example of comparison of the daily costs of different strategies, it is proved that the optimal control strategy can be sure to meet the load demands and reduce its operating cost effectively.
